It is a fact that human beings reflect upon their own acts, pronouncing them, according to the result of this reflection, good or bad. How are such judgments as these possible?

We will suppose, first, the simplest conceivable case, namely, that the acting subject pronounces judgment on his own act without consideration of the existence of other beings. Such a judgment must presuppose memory; but it presupposes something more, namely pain or pleasure through memory; an end is aimed at only because the thought of a result causes pleasure. In the simple case supposed, the feeling which determines the end can be only that of the individual himself, and the latter will judge the act as good or bad according as it has affected his own life. The character and significance of the judgment will depend on whether the feeling of pain or pleasure is determined only by the single moment or has reference to the life of the individual as a whole. The lower the life of consciousness, the more isolated and independent are the single moments of time in relation to each other, and the less is the significance of the memory and the thought of the ego as a whole embracing the single moments with their content. Only a half-unconscious instinct hinders the individual from losing himself in the moment; the instinct of self-preservation leads him to consider the future and to make use of the experience of the past. The more he loses himself in the moment, the less is the power of judgment, since comparison and action and reaction of the different states cannot take place. The single moment bears to all others the relation of an absolute egoist, who does not wish to relinquish any part of its satisfaction for their advantage.

And here we may perceive the possibility of a standpoint upon which all judgment is dispensed with. Such a standpoint is represented by Aristippus of Cyrene, who asserts the sovereignty of the moment. It is not without its justification. Ethics itself must show cause for the relinquishment of the satisfaction of the moment in favor of other moments.

If the principle of the sovereignty of the moment could be practically carried out, no reasoning could overthrow it. However, there can scarcely be a conscious individual in whom there are not instincts and impulses which reach beyond the moment. When a momentary state of feeling, as the effect of an act of the subject, comes together in consciousness with the feeling determined by the conception of the life as totality (the result of memory and comparison), a new feeling arises which is either one of harmony or one of discord. The standard by which judgment is pronounced is determined by this feeling. The capacity for such feelings is conscience, as this may manifest itself in entirely isolated individuals. Conscience, in the broadest sense of the word, is a feeling of relations, and requires only a relation between central and peripheral feelings,—feelings of wider, and feelings of narrower thought-connection. The single moment and the single act are judged according to their worth as parts of the individual life as totality.

And here the individual is confronted by the necessity of bringing the single parts of his life into harmony. The problem is certainly never solved by any individual involuntarily. The estimation of earlier acts according to the assistance they give in this task is, therefore, at this point, of great importance to the individual. The judgment pronounced is thus not only made possible through the central feeling which corresponds to the life as totality, but is determined by it. An acute sense for that which benefits the individual life whose single members are the moments, is a condition of the continuance and development of the life; it is a higher sort of instinct of self-preservation, and need not be confined to the continuance of physical life, but may also refer to the ideal needs.

And here we come upon the standpoint of Individualistic Ethics. From such a standpoint, the problem is to determine, not only how much energy may be used in the single moments of time, but also in what manner it should be used in order to secure as great variety and many-sidedness as may be consistent with the interests of the life as totality. Nor are the interests of the life to be summed up in physical self-preservation; the individual acquires, in the natural course of things, interests of increased ideality and complexity, through which the life gains in content.

The ethical law, from the standpoint of Individualism, is expressed by a formula which requires harmonious relation between the interest of the life as totality and the impulse of the moment; it consists of two chief mandates: (1) The single instant should have no greater independence than corresponds to its significance in the life as totality; (2) but, on the other hand, the single moments should be as richly and intensely lived as is consistent with the preservation of the life's totality.

Of Individualism, or the principle of the Sovereignty of the Individual, the same is true as of the sovereignty of the moment, that no reasoning can overthrow it; if the individual recognizes no end but his own life, there is no logical way of transition to another standpoint. A change of aim can take place only through such a change in the central feelings which determine the standard of the individual that a wider circle of conceptions enter into his reflections. Until this takes place, there is no use in appealing to conscience.
